摘要: This paper describes the complete design and implementation of a digital controller for high-frequency switching power supply. Guidelines minimum required resolution analog-to-digital converter, pulse-width modulator, fixed-point computational unit are derived. A example based on buck converter operating at frequency 1 MHz is presented. The direct approach standard root-locus techniques. Experimental results shown to validate allocation resources (resolution) in implementation.
